Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is the
main reason of hospital admission. Early diagnosis and prognostication of patients
are important to guide clinicians in optimal decisions regarding the type and site of
care. Different scores used to assess the severity of exacerbation and predict the
outcome. This study aimed to assess the value of four scores (DECAF, BAP-65,
CURB-65 and qSOFA) in predicting intensive care unit admission and in-hospital
death in patients with AECOPD.
